  4. 10 Points Lead is a bluish-white metal that will burn in air to produce lead (II) oxide. It is highly malleable and was used by the Romans to make pipes to carry water ("plumbing" is taken from the Latin name for lead "plum bum"). It has a relatively low melting point of 327°C and an atomic weight of 207.2 amu. Which property of lead is a chemical property? high malleability burns in air low melting point atomic weight is 207.2 amu

  5. WRONG ANSWER

  6. burns in air

  7. 20 Points In order to determine the velocity of an object, what measurements must be made? time and distance time, distance, and mass time, distance, and direction time, distance, and volume

  8. TRY AGAIN

  9. time, distance, and direction

  10. 30 Points An analogy can be drawn between the work done by an electric current flowing through an electrical appliance and the work done by water flowing over a waterfall. In such an analogy, identify the property of the electric current that is analogous to the rate of flow of water over the fall. power voltage amperage resistance

  11. The answer you thought was right is WRONG

  12. amperage

  13. 40 Points Identify the types of fields that interact to produce motion in an electric generator. an electrical field and a gravitational field a magnetic field and an electrical field two electrical fields two magnetic fields

  14. Try again later

  15. a magnetic field and an electrical field

  16. 50 Points Identify the type's of current that can be used to power electric motors. direct current only absolute current only direct current or alternating current only alternating current, direct current or absolute current

  17. Wrong again

  18. direct current or alternating current only

  19. 10 Points Complete the following reaction. NaOH(aq)+HCl(aq)=_____+H2O(l) 2NaCl(1) NaCl(s) NaCl(aq) 2NaCl(aq)

  20. BOO !

  21. NaCl(aq)

  22. 20 Points Which of the following will have the lowest pH? rainwater distilled water soapy water bleach

  23. Sorry, Wrong Answer

  24. rainwater

  25. 30 Points Dr. M wants to perform research on the effects of exposure to gamma radiation. Dr. B has developed a new type of instrument that fires gamma radiation at tumors; he wants to research the effectiveness of his "gamma knife." What is the fundamental difference between the research performed by these two doctors? Dr. M must know about nuclear decay, and Mr. B doesn't need to. Dr. M's research is ethical and Dr. B's is not. Dr. M is conducting a scientific investigation and Dr. B is not. Dr. B is focusing on technological design and Dr. M is not.

  26. GO BACK, and try again

  27. Dr. B is focusing on technological design and Dr. M is not.

  28. 40 Points Alan constructs a circuit that has two 1.5 V batteries arranged in series. These batteries power a single light bulb. What will happen if Alan adds another load in series? The resistance of the circuit has increased, so more current will flow. The voltage of the circuit has increased, so more current will flow. The resistance of the circuit has decreased, so less current will flow. The resistance of the circuit has increased, so less current will flow.

  29. SORRY 

  30. The resistance of the circuit has increased, so less current will flow.

  31. 50 Points Which of the following substances is the most chemically stable? Mg2+ Mg+ Cl- MgCl2(s)

  32. Wrong Answer

  33. MgCl2(s)

  34. 10 Points What is the danger of an uncontrolled chain reaction within the core of a nuclear fission reactor? An uncontrolled chain reaction will use up all of the fuel in the reactor and force the fission of the metals that make up the core casing. An uncontrolled chain reaction will produce enough heat to crack the reactor core open, releasing radioactive material. An uncontrolled chain reaction will produce enough electrons to electrically charge the reactor core. An uncontrolled chain reaction will produce enough heat to induce fusion in the reactor core, which will result in an explosion.

  35. Sorry, you have the wrong answer

  36. An uncontrolled chain reaction will produce enough heat to crack the reactor core open, releasing radioactive material.

  37. 20 Points The loss or gain of which subatomic particle has the greatest effect on chemical reactivity? electron proton Neutron nucleon

  38. Try again later

  39. electron

  40. 30 Points What question did the students pose before designing this experiment? How does temperature affect the rate of the breakdown of hydrogen peroxide into water and oxygen? How much dye do I need to use to determine the presence of hydrogen peroxide while performing this experiment? How many plants should I put in the laboratory to have an abundance of oxygen in the air? How does time affect the increase in temperature when hydrogen breaks down into oxygen and water?

  41. SORRY, wrong answer

  42. How does temperature affect the rate of the breakdown of hydrogen peroxide into water and oxygen?

  43. 40 Points For new scientific knowledge to be gained, scientists must share their ideas. What is an appropriate way for scientists to communicate their findings? Make flyers advertising their results. Write a book immediately after the experiment is conducted, pronouncing the discovery as fast. Hold a press conference to share the information gained. Submit complete information regarding the experiment to a peer-reviewed scientific journal.

  44. Wrong, wrong and WRONG !

  45. Submit complete information regarding the experiment to a peer-reviewed scientific journal.

  46. 50 Points When energy is transformed from one form to another, some of the energy is lost in the form of mechanical energy. hydrogen gas. water. thermal energy.

  47. Nope, not the right answer

  48. thermal energy.

  49. 10 Points Joey hit a wall with a 1 meter long sledgehammer 20 times with a force of 200 Newton's. Much to Joey's dismay, the wall remained undamaged. If work = force X distance, how much work did Joey do on the wall? 0 joules 10 joules 200 joules 4000 joules
